Modeling the Effect of Penetrator Nose Shape on Threshold Velocity for Thick Aluminum Targets.

Abstract

This study examines the ability of the CTH hydrocode to predict the effects of rod nose shape on the threshold impact velocity, whereby tungsten alloy long rods transition from rigid-body to eroding-rod penetration during penetration or perforation of thick aluminum targets. Two rod nose shapes (hemispherical and ogival) were used in the simulations, and two aluminum alloys (5083 and 7039) were used as the target materials. The predicted results are compared to an experimental study. Predictions of the threshold velocity for the ogival-nose rod are offered.
